本発明は、インフュージョンハブアセンブリおよび流体ライン切断システムに関する。 The present invention relates to an infusion hub assembly and a fluid line cutting system.
本発明は、35U.S.C.セクション119に基づく、2001年3月4日出願の出願番号60/273,490および2,001年6月19日出願の出願番号60/299、842の、米国暫定特許出願に対する優先の利益を要求する。 The present invention relates to 35U. S. C. Request priority benefits for US Provisional Patent Application No. 60 / 273,490 filed March 4, 2001 and Application Number 60 / 299,842 filed June 19, 2001 under section 119 To do.
種々の態様において、本発明はインフュージョンハブアセンブリを提供する。
このアセンブリは、貫通ホールを有するウィング;前記ウィングの貫通ホールに受容されるハブ、そして前記ハブはこれを貫通するボア、および取付面を有する前記円形ハブの上部を有する;前記ウィングから下方に離れて延びるカニューレ、前記インフュージョンカニューレは前記ハブを貫通するボアに流体連通する;貫通するボアを有し、前記ハブの上部上に取付面に結合するように調整された内取付面を有するカバー、;および前記カバーを貫通する前記ボアに一列に配置されたセプタムを有する。
In various aspects, the present invention provides an infusion hub assembly.
The assembly includes a wing having a through hole; a hub received in the through hole of the wing; and the hub has a bore therethrough and an upper portion of the circular hub having a mounting surface; spaced downward from the wing Extending in a cannula, wherein the infusion cannula is in fluid communication with a bore through the hub; a cover having a bore therethrough and having an inner mounting surface adapted to couple to a mounting surface on the top of the hub; And a septum arranged in a row in the bore penetrating the cover.
種々の態様において、前記ハブの上部は円形であり、周囲に延びる取付面を持っている。種々の態様において、この取付面は周囲に延びるリップを有する。 In various embodiments, the upper portion of the hub is circular and has a mounting surface extending therearound. In various embodiments, the mounting surface has a peripherally extending lip.
本発明のインフュージョンハブアセンブリはボアを有するカバーを具え、患者の皮膚上にアセンブリのウィングを最初に配置する際、皮下に延びるインフュージョンカニューレと共に、このボアを通って挿入ニードルが配置される。種々の態様において、前記カバーはセプタムを保持して患者への経路を有利にシールする(挿入ニードルが貫通していない場合)。 The infusion hub assembly of the present invention includes a cover having a bore, and an insertion needle is placed through the bore with an infusion cannula extending subcutaneously upon initial placement of the assembly wing on the patient's skin. In various embodiments, the cover holds the septum and advantageously seals the path to the patient (when the insertion needle is not penetrated).
種々の態様において、カバーの寸法はインフュージョンハブを覆ってスナップフィットするようにする。種々の態様では、カバーは中央ボアを持っており、アセンブリが皮下に配置される場合にインフュージョンニードルがこのボアを通る。 In various embodiments, the cover dimensions are snap fit over the infusion hub. In various aspects, the cover has a central bore through which the infusion needle passes when the assembly is placed subcutaneously.
その後、新規な回転可能インフュージョンハウジングをカバーの頂部に取り付ける。種々の態様では、回転可能ハウジングは、カバーの上部の外側取付面に結合するように調整された取付面を持っている。したがって、種々の態様では、回転可能ハウジングもカバーを覆ってスナップフィットするように寸法決めされる。カバーはインフュージョンハブを覆って順にスナップフィットされる。 A new rotatable infusion housing is then attached to the top of the cover. In various aspects, the rotatable housing has a mounting surface that is adjusted to couple to an outer mounting surface on the top of the cover. Thus, in various aspects, the rotatable housing is also sized to snap fit over the cover. The cover is snap fitted over the infusion hub in turn.
種々の観点では、カバーおよび回転可能ハウジング両方の上の取付面は、それらの周囲に周縁的に延びるリセスを有する。これらのリセスはインフュージョンハブおよびカバーの上部から延びるリップにそれぞれ結合する。種々の観点では、インフュージョンハブおよび回転可能ハウジングは、回転可能ハウジングが自由に回転でき、かつ依然、患者に皮下的に薬剤(または他の所望の流体物質)を連続注入できるように円形である。 In various aspects, the mounting surfaces on both the cover and the rotatable housing have recesses extending circumferentially around them. These recesses are respectively connected to the infusion hub and a lip extending from the top of the cover. In various aspects, the infusion hub and rotatable housing are circular so that the rotatable housing can rotate freely and still allow continuous infusion of medication (or other desired fluid substance) subcutaneously into the patient. .
種々の態様において、回転可能ハウジングは、ハウジング内の半径方向ボアを少なくとも部分的に通るカーブしたニードルを有し、このカーブしたニードルの先端は、回転可能ハウジングをカバーに取り付けた場合、カバーおよびハブ内のボアへ下方に向かって位置する。さらに、インフュージョンチューブはカーブしたニードルに流体連通して回転可能ハウジングの半径方向ボアに受容される。 In various aspects, the rotatable housing has a curved needle that passes at least partially through a radial bore in the housing, and the tip of the curved needle covers the hub and the hub when the rotatable housing is attached to the cover. Located down the inner bore. In addition, the infusion tube is received in the radial bore of the rotatable housing in fluid communication with the curved needle.
自由に回転でき、なお患者へ皮下的に連続的注入を提供する、回転可能インフュージョンハウジングを有する利点は、(1)インフュージョンチューブのよじれを回避し、(2)患者へインフュージョンハウジングをテープ止めする必要を回避し、これにより、(3)患者の体の異なる位置にインフュージョンポンプ(これは流体をインフュージョンチューブに供給する)を位置させることが可能になる。
The advantages of having a rotatable infusion housing that can rotate freely and still provide continuous infusion subcutaneously to the patient are (1) avoiding kinking of the infusion tube and (2) tape the infusion housing to the patient avoiding the need to stop, which makes it possible to position the (3) an infusion pump in different positions of the patient's body (which supplies fluid to the infusion tube).
本発明の別の観点では、本発明はインフュージョンコネクタセットを提供する。このセットは、基部コネクタ、この基部コネクタに受容されるセプタム、先端コネクタ、先端コネクタに受容されるセプタム、および基部コネクタおよび先端コネクタを一緒に連結した場合、基部コネクタおよび先端コネクタの両セプタムを貫通するフランジニードルを有する。 In another aspect of the present invention, the present invention provides an infusion connector set. This set penetrates the base connector, the septum received by the base connector, the tip connector, the septum received by the tip connector, and both the base connector and the tip connector septum when the base connector and the tip connector are connected together A flange needle.
しかし、本発明で「基部」および「先端」コネクタに対してなされた参照部分は単に例示であることが理解されるであろう。したがって、その代りに、フランジニードルは、基部コネクタ内より寧ろ先端コネクタ内で種々の位置に移動することができる。したがって、本発明は「第1」および「第2」コネクタを参照する。種々の態様では、「第1」コネクタは「基部」コネクタであり、「第2」コネクタは「先端」コネクタである。代替的な態様では、コネクタは「第1」コネクタが「先端」コネクタであり、「第2」コネクタが「基部」コネクタであるように逆になる。 However, it will be understood that the reference portions made to the “base” and “tip” connectors in the present invention are merely exemplary. Thus, instead, the flange needle can be moved to various positions within the distal connector rather than within the base connector. Accordingly, the present invention refers to “first” and “second” connectors. In various aspects, the “first” connector is a “base” connector and the “second” connector is a “tip” connector. In an alternative aspect, the connectors are reversed such that the “first” connector is a “tip” connector and the “second” connector is a “base” connector.
種々の態様では、フランジニードルは先端コネクタのスロット内をスライド移動可能である。種々の観点では、フランジニードルに保持される位置に動くことができる。 In various aspects, the flange needle is slidable within the slot of the tip connector. In various aspects, it can move to a position held by the flange needle.
したがって、基部および先端コネクタを一緒に固定した場合、ニードルはこれを通る流体通路を提供する。先端コネクタを基部コネクタから外している場合、先端コネクタ内のセプタムは封止されるであろう(フランジニードルは基部コネクタ内に保持され、これによりもはや先端コネクタ内のセプタムに接触しないからである)。 Thus, when the base and tip connector are secured together, the needle provides a fluid passage therethrough. When the tip connector is disconnected from the base connector, the septum in the tip connector will be sealed (because the flange needle is held in the base connector and thereby no longer contacts the septum in the tip connector) .
種々の態様では、フランジニードルのフランジは、オペレータがフランジをつかんでフランジ針を先端コネクタ内のスロットに沿って動かすことができるように先端コネクタ内のスロットを通って突き出る。このようにして、フランジニードルを、ニードルが基部コネクタ内のセプタムをもはや貫通しない位置に便利に動かすことができる。したがって、基部コネクタのセプタムは自己封止され、インフュージョンチューブを介して配送される物質に対して汚染または暴露を防止する。 In various aspects, the flange of the flange needle protrudes through a slot in the tip connector so that an operator can grab the flange and move the flange needle along the slot in the tip connector. In this way, the flange needle can be conveniently moved to a position where the needle no longer penetrates the septum in the base connector. Thus, the septum of the base connector is self-sealing, preventing contamination or exposure to materials delivered through the infusion tube.
互いから容易に非連結にできる、(両コネクタを通る流体通路を封止するそれぞれのセプタムを具えた)基部および先端コネクタを有する利点は、異なるインフュージョンライン間を容易に切替できることである。 The advantage of having a base and tip connector (with respective septa sealing the fluid passages through both connectors) that can be easily disconnected from each other is that they can be easily switched between different infusion lines.
それ自体のセプタムを具える先端コネクタを提供するさらに別の利点は、患者が基部および先端コネクタを手動で連結を外すことができ、そして先端コネクタのセプタムを介して患者に(別の薬剤または物質を含む)シリンジ注入することである。 Yet another advantage of providing a tip connector with its own septum is that the patient can manually uncouple the base and tip connector and to the patient via the tip connector septum (another drug or substance). Syringe injection).
種々の態様では、インフュージョンコネクタセットは、基部コネクタの先端に取り付けられたリテイナをさらに有する。種々の態様では、このリテイナは、フランジニードルの動きを、基部コネクタ内で上下動を保持するように、基部コネクタのスロットの先端を閉じる。 In various aspects, the infusion connector set further includes a retainer attached to the distal end of the base connector. In various aspects, the retainer closes the distal end of the slot in the base connector so as to keep the movement of the flange needle up and down within the base connector.
種々の態様では、基部および先端コネクタは、一方のコネクタが他方に挿入され、インターロック位置に回転するように、寸法決めされる。このことは、コネクタの一方がそこから延びる少なくとも1つのツメを具え、コネクタの他方がその中に少なくとも1つのリセスを具えることにより達成される。この少なくとも1つのリセスは、基部および先端コネクタを一緒に連結した場合、そのなかに少なくとも1つのツメを受容するように寸法決めされる。種々の態様では、少なくとも1つのツメを有するコネクタは基部コネクタであり、少なくとも1つのスロットを有するコネクタは先端コネクタである。 In various aspects, the base and tip connectors are dimensioned such that one connector is inserted into the other and rotated to the interlock position. This is achieved by one of the connectors having at least one claw extending therefrom and the other of the connector having at least one recess therein. The at least one recess is dimensioned to receive at least one claw therein when the base and tip connector are coupled together. In various aspects, the connector having at least one claw is a base connector and the connector having at least one slot is a tip connector.
添付の図面と共に以下の詳細な態様の説明を読むことによって当業者には本発明の他の特徴および利点がなお明らかになるであろう。
図1〜6は本発明のインフュージョンハブアセンブリを示す。図7〜15は本発明のインフュージョンコネクタセットを示す。
Other features and advantages of the present invention will become apparent to those of ordinary skill in the art by reading the following detailed description of the embodiments in conjunction with the accompanying drawings.
1-6 illustrate the infusion hub assembly of the present invention. 7 to 15 show the infusion connector set of the present invention.
先ず、図1〜6を参照する。インフュージョンハブアセンブリ10を提供する。大きいウィングまたはパッチ12はそれを貫通するホール13を有する。ウィング12は患者の皮膚表面に配置される。種々の態様において、ウィング12の下側は接着面を持ち、患者の皮膚に固定される。代替的態様において、ウィング12は患者の皮膚に直接テープ留めされる。
First, reference is made to FIGS. An
図1に示すように、アセンブリ10はウィング12、ハブ14およびカバー18を有する。種々の観点において、ハブ14の全部かまたは少なくとも上部は円形である。ハブ14は、ウィング12の円形ホール13内に受容される。種々の態様において、図示するように、ホール13は直径が段階的であり、円形ハブ14も、ハブ14がホール13に固定するように段階的な直径を持っている。円形ハブ14は垂直に貫通する中央ボアを持つ。ニードルガイド16は、図示のとおり、円形ハブ14を貫通するボア内に位置する。ニードルガイド16は漏斗形でもよく、金属製でもよい。
As shown in FIG. 1, the
種々の観点において、円形ハブ14の上部には取付面があり、この上にカバー18をスナップフィットできる。例えば、種々の観点で、円形ハブ14はその周囲に少なくとも部分的に周縁に延びるリップ15を有する。種々の態様では、カバー18はその周囲に少なくとも部分的に周縁に延びる内部溝19を有する。種々の態様において、カバー18は円形ハブ14の上部にかぶせて容易にスナップフィットできるように可撓性材料製である。
In various aspects, there is a mounting surface on the top of the
図示のように、セプタム20を提供する。セプタム20はカバー18で保持してもよい(カバー18をハブ14から除去するとき、セプタム20も除去されるように)。図示のように、セプタム20は、カバー18をハブ14にかぶせて配置される場合、ニードルガイド16内に受容されるように、配置される。セプタム20は、自己封止弾性材料のプラグから作ることができる。
As shown, a
インフュージョンカニューレ22はウィング12から下方に延びる。したがって、インフュージョンカニューレ22は、ウィング12を患者の皮膚に載置した場合、皮下に位置される。このようにして、インフュージョンカニューレ22は患者に薬剤を皮下的に注入するために使用される。種々の態様において、インフュージョンカニューレ22の近接端部は円形ハブ14の下方部内に受容されて配置され、ニードルガイド16の端部周りに受け取られる。しかし、図示のように、本発明では、このように限定するものではない。ウィング12から下方に延びるように、インフュージョンカニューレ22を取り付けるための多くの他の装置をも本発明の範囲内に含む。
The
次に、図2を参照する。インフュージョンカニューレ22が皮下的に配置されるようにアセンブリ10を配置するための種々の処置をも提供する。特に、インフュージョンニードル30(これはハンドル32により支持される)は、保護カバー18および円形ハブ14の中央ボアを貫通して挿入される。このように、ニードル30がセプタム20を貫通して、下方に延び、インフュージョンカニューレ22の底部先端部から突き出る。図2に示すように、ニードル30をインフュージョンカニューレ22から挿入する場合、オペレータは、ウィング12を患者の皮膚に接触させて押し下げ、インフュージョンカニューレ22が皮下に挿入されるように、ハンドル32に対して簡単に下方に押圧する。
Reference is now made to FIG. Various procedures are also provided for placing the
ウィング12を患者の皮膚に載置し、インフュージョンカニューレ22を皮下に配置してアセンブリ10を配置した後(即ち、図2に示すように)、オペレータはハンドル32を上方に引き上げることにより、簡単にニードル30を除去する。ニードル30を最初に除去する場合、セプタム20は自己封止して、大気からカニューレ22を通って、患者の皮下の皮下経路に汚染物が侵入することを確実に防止する。
After the
ニードル30を除去した後、以下のように、回転可能なインフュージョンハウジング40により置き換えられる。
After the
図3に示すように、その後、回転可能なハウジング40をカバー18にかぶせて取り付ける。回転可能ハウジング40は、カバー18をかぶせてスナップフィットできるように可撓性材料製である(カバー18をハブ14にかぶせて固定する方法と類似している)。特に、回転可能ハウジング40も、周囲に少なくとも部分的に周縁に延びる内側溝41のような内側取付面を有する。
As shown in FIG. 3, the
カバー18のリップ17周囲に少なくとも部分的に周縁に延びる内側溝41の利点は、ハウジング40が円形ハブ14に対して回転可能であることである。したがって、図4および5に示すように、ハウジング40は方向Rに自由に回転できる。
The advantage of the
図3に戻る。インフュージョンチューブ50を使用して薬剤(または他の所望の物質)を患者に皮下的に分配する。チューブ50はハウジング40内の半径方向に延びるボア42に受け取られる。カーブしたニードル44はチューブ50の端部に取り付けられ、下方を向いたその先端部が直接ハブ14のボア内のニードルガイド16内に受け取られるように配置される。カーブしたニードル44の先端は回転可能ハウジング40の中央から下方を向き、カバー18およびハブ14を貫通して中央ボア内に位置されるので、ハウジング40はその中央軸周りにR方向に自由に回転できる。一方、薬剤または他の所望の物質はチューブ50を介して注入される。
Returning to FIG. The
図6は、本発明装置の分解図を示す。ここにおいて、(i)導入ニードル30、または(ii)回転可能ハウジング40およびインフュージョンチューブ50、のいずれかをカバー18に取り付けてセプタム20を介してハブ14に通す。図示のように、種々の態様において、カニューレを保護し、使用前にカニューレが汚染しないように、任意的な除去可能保護シリンダ23をインフュージョンカニューレ22にかぶせて受け取ることができる。
FIG. 6 shows an exploded view of the inventive device. Here, either (i) the
図7〜15に移る。インフュージョンコネクタセットをも提供する。種々の観点において、コネクタアセンブリ100は基部コネクタ110および先端コネクタ120を有する。ユーザの嗜好に応じてコネクタ110は先端コネクタの代りになることができ、コネクタ120は基部コネクタの代りになり得ることが理解される。示すように、アセンブリ100を使用してインフュージョンチューブ50に沿った取り外し可能な結合リンク中間路を提供する。しかし、コネクタアセンブリ100(図7〜15)をインフュージョンハブアセンブリ10(図1〜6)に接触して使用できるが、これは必要ないことがわかる。寧ろ、コネクタアセンブリ100およびインフュージョンハブアセンブリ10のおのおのは別々に使用される。したがって、図1〜6の符号「50」は図7〜15における符号「50」のチューブと同じであっても異なっていてもよい。
Turning to FIGS. An infusion connector set is also provided. In various aspects, the
図7は、一緒に結合された基部コネクタ120および先端コネクタ110を示す。図8は互いに非結合の、基部コネクタ120および先端コネクタ110を示す。説明通りに、本発明のコネクタセットは、先端コネクタおよび基部コネクタを一緒に結合した場合、流体はアセンブリを通って自由に流れる装置を提供する。基部および先端コネクタはもはや固定されず、あるいは一緒に結合されない場合に、本発明は、基部または先端コネクタのいずれかを通る流路に汚染物が入ることを防止する新規な自己封止装置を提供する。特に、説明通り、自己封止セプタムが基部および先端コネクタのおのおのに配置される。さらに、基部コネクタが、基部ニードルにおけるセプタムが、望む通りに自己封止されるように動くことができるフランジニードルアセンブリを支持する。
FIG. 7 shows the
図10を参照する。基部コネクタ110は、その中に受容されるセプタムハウジング111を有する。自己封止セプタム112はセプタムハウジング111により適所に保持される。そして、フランジ114およびニードル113を有するフランジニードルアセンブリはその中に受容される。説明通りに、フランジ114は、基部コネクタ110のスロット115を上下動できる(これにより、異なる位置にニードル113が動く)。その後、リテイナ116がフランジニードルアセンブリ113/114を覆って受容される。リテイナ116はフランジ114がスロット115から外れることを防止する。このようにして、ニードル113は何時も基部コネクタ110内に支持される。
Please refer to FIG.
図11を参照する。先端コネクタ120はその中にセプタムハウジング121を有する。自己封止セプタム122はセプタムハウジング121により適所に保持される。
Please refer to FIG. The
一緒にアセンブリされた場合、図7に示すように(および図12および13に示すように)、ニードル113はセプタム111および121の両方を貫通して、チューブ50を介した流れを可能とする。
When assembled together, as shown in FIG. 7 (and FIG. 12 and 13), the
コネクタを互いに非接続にする場合(即ち、先端コネクタ120を基部コネクタ110から取り外す場合)、ニードル113(基部コネクタ110内に保持される)はもはや先端コネクタ120内の先端部セプタム121を貫通しない。したがって、先端部セプタム121は、患者への皮下経路(すなわち、先端コネクタ120、チューブ50および回転可能ハウジング40を介する患者への経路)が封止されるように、自己封止する。しかし、ユーザが望む場合には、異なるまたは付加的な薬剤(または他の物質)を患者へ皮下的に導入できるように、先端コネクタ120の先端部セプタム121を通って別の注射針を挿入できる。
When the connectors are disconnected from each other (ie, when the
本発明では、基部コネクタ110の基部セプタム111を封止する新規な装置をも提供する。図9(および図14および15)を参照する。もはや基部セプタム111を貫通しない位置にニードル113を動かすように、フランジ114をスロット115に沿って先端方向に動かす。
The present invention also provides a novel device for sealing the
種々の態様において、オペレータがフランジ114をつかんで、リテイナ116に対して適所にスライド可能にするために(ニードル113がもはやセプタム111を突き刺さないように)、フランジ114は基部コネクタ110の対向両側部のスロット115を介して僅かに突き出ている。
